What is the European Court of Human Rights
The European Court of Human Rights has jurisdiction in the 46 countries that are subscribed to the European Convention of Human Rights.
Based in Strasbourg, its judges rule on possible breaches of the 16 Articles that make up the Convention.
It emerged from the Second World War and has been in place since 1953 where Britain was a founding member.
The court is entirely separate from the European Union meaning the UK is still bound by its rulings.
Large sections of the Convention are enshrined in UK law via the 1998 Human Rights Act.
Why do critics want to leave it?
In recent years there have been growing calls to leave the ECHR, which critics accuse of becoming increasingly political.
This culminated in 2022, when an anonymous judge ordered the British government to abort its first Rwanda flight while the plane was on the runway.
Fears of overreach also boiled over last week when Strasbourg ruled against the Swiss Government for not doing enough to stop climate change.
Proponents of the ECHR say leaving would put Britain in the same club as Russia and Belarus as the continent’s only non-members.
But critics like Liz Truss hit back that many countries such as the United States, Canada and Australia have good human rights without needing a third party court.
What has Rishi Sunak said?
Rishi Sunak has said he would be prepared to quit the ECHR if that is what it takes to stop the boats.
He told our Never Mind The Ballots show: “I believe that border security and controlling illegal migration is more important than our membership of any foreign court.”
Separately, the Rwanda Bill gives ministers the powers to ignore the so-called “Pyjama Injunctions” which lets judges cast down eleventh-hour vetos in the dead of night.
